Letters Patent No.v104,742, dated .Tu-ae 28, ,1870.

.IMPRovED APPARATS PoR ELEVATING BEER.

The Schedule referred to in .these-Letters Patent and making part of the same I the water is -forced into the air-vessel and through suitable pipes'into the be, -barrels, and by its pressnre forces the beer througl the ordinary pipes ltothe bar-room. g

When a'suficient amount of airis made Aavailable `for the purpose, the communication with the hydrant The water and air-pipes are"provided with cocks, for opening and closiu g them, as hereinafter described.

The water-receiving vessel is also provided with a float which operates a valve to .closeth'e mouth of the air-pipe, before the water has risen high enough to runinto the air-vessel, to prevent the passage `of the water to said vessel.

improvement appertainst'o make and use our invention, we will now give a detailed description thereof.

Figure 1 'is -a plan viewot' the apparatus. Figure 2 is a side elevation of the same.' Like letters in both iigures indicate the sameparts. A is the air-vessel. l p 'B 'is a water-vessel connected with the said air vessel by means of the pipe C at the upper end, and it connects with a hydrant, not shown in the drawing, by meansof the pipe D.

A communication is opened between the air-vessel A and the beer-barrelsby means of a pipein connec tion with the faucet E, whereby the beer is force through the ordinary pipes tofthe bar-room. i Q

lhe ai'rpipe C and waterpipe Dare provided 'with three-way cocks, F and F', whichfare operated by the duplex keys G and G', attached to the vertical rod H having a hand-wheel, I. f If it should be desirable to have the apparatus'under the control of a person in the bar-room, to avoid the necessity of his going to the cellar'or storage room to operate it, there may be 'a vertical rod with a socket at its lower end connected with the square luga on the key Gr, the said rod being provided with a ,hand-wheel on its upper end for its manipulation'.

When-the dater is to be turned into the Wessel B' 13th day of Api-i1, 1870.

from the hydrant, by turning the hand-wheel I in the direction of the arrow, the keys Gr and G are brought 4into the position represented in the drawing, whereby there is a free opening of the pipes O and D, The solid side of 'the keys are, at this time, against the pipes Kand K', which are used for letting air into the vcsseLB at the 'upper end andthe discharge of the water from the lower end of .the vessel, when the said vessel has to be emptied.-

By areverse motion of the hand-wheel, the communication, with the air-vessel A and hydrant is closed, and the communication with the pipes K and K- is opened, the air passing into the vessel through the pipe K, assisting in the discharge ot' the water.

through the pipe K';

vFor preventing the water :flowing from the vessel B into the air-vesselA, when it rises as high at themout-h of the pipe O, there is a valve, L, provided' with the'oat M. The valve remains open until .tlrewaterrises into the upperpart otthe vessel B, as'

seen in full lines, but, when the water bears up the oat, the valve closes, 'thus preventing the escape oi' water into the air-vessel.

The pipe O is provided with a valve, N, which is A i elevated lfrom its seat, 11, as seen in fig. 2, by the press- To enable others skilled in the` artA to which' ourA ure of the air in the vessel B, so,as to opentle come mnnicatiouwith the'air-vessel A for the passage of' the air into the same. When'the pressure of air 1n `the vessel B is removed, the valve falls down on its seat and prevents the return of .air from the vessel Av tothe vessel B.

O is a blow-ofi' cock to the.vessel A.

What we claim as new, and desire to secure by Lctters Patent, is

1. The duplexvkeys G and G connected together by means of .the rod-H, when arranged and operating inrelation to the cocks F and 14", substantially in the manner' and for the purpose set forth. 4

2. The combination of the air-vessel A, water-vessel B, pipes C D K and K?, cock F and F, valve L and oat M, all constructed, arranged, and operatinf. in relation to each other, substantially in the manner and for the'purpose specified.

In testimony that the aboveis our invention, we have hereunto set our hands and affixed our seals this ALBERT H. LADNER. [n 5.] THOMAS. Ir. IPENLIN. {ne} `Witnesses:
